Bellcore DTMF talk-off test tapes

Hello,
I'm working on testing a DTMF detector implemented in an FPGA.
Bellcore (formerly AT&T?) used to sell talk-off test tapes to test
DTMF decoder. However, they don't sell them anymore. Even worse, the
rumour is the master tapes where lost. I tried to contact the current
owners of the Bellcore material, but got no response. Is there someone
willing to provide me with a copy or sell the original tapes?

You may have better luck finding the Mitel version (CM 7291). I did a little
digging, but couldn't find either. However, lots of people still refer to it
(them) so there MUST be someplace to get it. I'll bet there's even a .wav
file available, somewhere.

I used to use the ATT tape. I should have kept a copy.

I'll keep looking, and I'll let you know if I find either.

I was able to find this:

http://assets.zarlink.com/DS/zarlink_CM7291_JAN_97.pdf

Zarlink (apparently) took over some of the Mitel telecom semiconductor
products. Although their talk-off tape is listed as "obsolete", I'll bet if
you call them they can give you a better idea if this can be obtained, or if
there's a suitable replacement.

Good luck.

Thank you. I also found some references to the Mitel tape, but no
product number. I will give Zarlink a call.
